Hey guys,

Has anyone on here had issues with there dsp not communicating with the pcm? I had intermittent issues at first with connecting when I first started tuning and now nothing at all just says unsupported vehicle. My tuner is up to date too. Any ideas?

Things I've checked so far: obd port pins, check continuity from the obd port to the pcm on the c1 connector I believe and those check out good. Checked bus voltage it came back less then a volt and the resistance of the bus with the battery neg disconnected came out around 700 ohms.
